2河南体彩快赢481走势图线路干扰。线路干扰是引起变压器事故的最重要因素。它主要包括开关过程中产生的过电压、低负荷阶段的电压峰值、线路故障、闪络等异常现象。这个故障在变压器的故障中占有很大的比重。因此,应定期进行冲击保护试验,以测试变压器的抗励磁电流强度。

3河南体彩快赢481走势图水分:如果洪水,漏管,屋顶漏水,燃料箱和绝缘油中水分的存在,例如沿外壳或附件的水分侵入。

4超载。变压器的过载是指比铭牌功率变压器多个操作条件下长时间。过载常发生在发电厂的情况下继续缓慢提升负荷,冷却装置工作不正常,变压器内部故障等,最终导致变压器超负荷运行。所得的过度的温度可导致衰老,纸强度降低后的绝缘,变压器绝缘板的过早老化。因此,外部故障的影响可能导致对绝缘损坏,并因此会发生故障。

3可靠性过程,特别是长期可靠性,在出厂试验中应是稳定的。环氧浇注是脆性材料,应提高环氧浇注构件的抗老化功能。

4产品寿数完结时的资料回收技能进步。当产品数量过多时,大量的铜、铝等数据灌注在环氧树脂中,很难从环氧树脂中剥离;如果高温剥离,能耗高;环氧树脂的分化也很困难。

5河南体彩快赢481走势图产品的安全性改进使产品的功能满足用户的需要,并能进行型式试验,特别是所生产的产品应与型式试验相一致。
